Subject: ntpd segfaults accessing IPv6 hosts

Hi full-disclosure!

ntpd 1:4.2.0a-11 (as in debian testing/sarge and unstable/sid) 
segfaults when accessing ntp servers on IPv6 hosts. I don't know 
whether this bug is exploitable. But such a server on 
pool.ntp.org might DoS many servers.

There is a fixed version available.

For more details see http://bugzilla.ntp.org/show_bug.cgi?id=353

Bernhard
